Habit | Herbs, perennial, 0.8–3.1 dm; from a woody caudex; with a taproot. | Herbs, perennial, 2.5–8(–10) dm; from a woody caudex; with a taproot or branched root system. |
Stems | several to many, erect to ascending, unbranched, sometimes branched near base, hairs spreading, long, soft, eglandular, mixed with dense, short stipitate-glandular ones. |
few to many, ascending to erect, unbranched or often strongly and diffusely branched distally, hairs sparse to dense, spreading to matted, long proximally on stem, becoming puberulent distally, ± stiff, eglandular, often mixed with retrorse shorter ones. |
Leaves | green, narrowly to broadly lanceolate or oblong-lanceolate, 9–35 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, distal sometimes 3-lobed, apex narrowly acuminate; lobes ascending or spreading, linear to lanceolate, apex acute to obtuse. |
green, linear-lanceolate or narrowly to broadly lanceolate, 2–6.5(–8) cm, not fleshy, margins plane, flat to involute, 0(–3)-lobed, apex acute; lobes ascending, lanceolate, apex acute to obtuse. |
Inflorescences | 3–9(–18) × 2–3 cm; bracts green to pale green to rarely dull purplish brown throughout, distally rarely with pale yellow apices, narrowly lanceolate to narrowly elliptic to sometimes broadly lanceolate, 3-lobed, wavy-margined; lobes spreading or ascending, narrowly lanceolate, medium length, arising at or above mid length, sometimes wavy-margined, apex obtuse to acute. |
(2.5–)5–15 × 2–4.5 cm; bracts proximally greenish, distally scarlet to red or orange-red, rarely yellow or crimson, veins usually yellow or yellow-green, contrasting conspicuously with base color, lanceolate or elliptic to oblanceolate or obovate, 0–3(–5)-lobed; lobes ascending, lanceolate to triangular, medium length, arising above mid length, apex rounded to obtuse. |
Corollas | conspicuously decurved distally, 18–22 mm; tube 11–14 mm; beak exserted, adaxially green to yellow-green or yellow, 6–8 mm; abaxial lip green, reduced, fleshy, included, 1.5–2 mm, 25% as long as beak, sparsely hairy, hairs spreading; teeth ascending, green, 0.5–1 mm. |
slightly curved, 15–35 mm, subequal to calyx or beak partially to strongly exserted; tube 15–17 mm; beak adaxially yellowish green, 10–16 mm; abaxial lip green, reduced, ± pouched, 0.5–1.5 mm, 4–10% as long as beak; teeth incurved, deep green, 0.7–1 mm. |
Calyces | green or yellowish green, 15–19 mm; abaxial and adaxial clefts 9–11 mm, 60% of calyx length, deeper than laterals, lateral 3.5–7 mm, 15–25% of calyx length; lobes broadly or narrowly triangular, taller than wide, apex acute to obtuse. |
mostly yellowish throughout, with a thin reddish apex, 15–27 mm; abaxial clefts (5–)9–11 mm, adaxial 4.5–9.5 mm, clefts 25–50% of calyx length, deeper than laterals, lateral 2–4 mm, 10–20% of calyx length; lobes linear-lanceolate to triangular, apex acute to acuminate, rarely ± obtuse. |

Discussion | Castilleja chlorotica is an uncommon to rare endemic on dry slopes in Deschutes, Klamath, Lake, and possibly Crook counties in central Oregon. The hooked corolla beak and greenish bracts, often aging purplish distally, help distinguish it from similar species such as C. glandulifera and yellow forms of C. applegatei var. pinetorum.

Castilleja nelsonii is fairly common in the upper elevations of the so-called sky island ranges from central and eastern Arizona to adjacent New Mexico, southward into the Sierra Madre Occidental, at least as far south as southern Chihuahua, where the type collection was obtained on Cerro Mohinora. Although it was long known in the United States as C. austromontana, the name C. nelsonii has priority. Some specimens from southern Coconino County, Arizona, approach C. miniata, but most material is easily separable. Castilleja nelsonii occasionally hybridizes with C. mogollonica in Apache County, Arizona, near the border of the range of the former.
